On a technical note, there is not legal age limit, but most retailers just don't sell to people under the age of 18 (I belive).
Cool to see that you have your level IV badge, but cadets don't mark their marksmanship levels very well, plus the rifles are in poor condition... But then I'm used to my nice crosman semi-auto gas air rifle...
On the way home from school today I saw some kids playing with clearsoft in the middle of the park near my house, there was no one around, but they wern't even wearing eye protection... I got out and lectured them, told them that it was unsafe... They just blew me off, so I told them that I'll follow them home next time and tell their parents how stupid their being. That got them to shutup and go away at least.
